## Finite undirected graphs which are not reconstructible from their large cardinality subgraphs.(English)Zbl 0759.05067

Summary: For any integer $$n_ 0$$ and any real $$q$$, $$0<q<1$$, we exhibit two nonisomorphic graphs on $$n>n_ 0$$ vertices having the same collections of $$m$$-vertex subgraphs where $$m$$ is the integral part of $$q\cdot n$$.
